Tray construction quality varies from manufacturer to manufacturer, but some of the common types and general benefits include: Fiberglass - perhaps the most durable of all tray materials, fiberglass trays often feature metal reinforcing rods to provide extra strength to eliminate the risk of warping. Dishwasher safe with a temperature range of 35°F to 200°F. Melamine - resistant to scratching, breaking, chemicals and food acids. Melamine quality may vary, but high quality melamine features a heavy, rigid material that often replicates the look and feel of chinaware. Dishwasher safe and dries quickly. Temperature range of 0°F to 212°F. Polycarbonate - also resistant to scratching, breaking and chemicals, polycarbonate trays are ideal for correctional facilities. Dishwasher safe with a temperature range of -40°F to 212°F Polypropylene - the economical option. Durably stands up to everyday use and is resistant to chemicals. Temperature range of 30°F to 180°F. Co-Polymer - also an economical choice, though not as durable as fiberglass, melamine or polycarbonate, co-polymer construction offers resistances to scratching or staining and is dishwasher safe. ABS - ideal for general, everyday use. Break and scratch resistant, dishwasher safe and a temperature range of 0°F to 180°F.
